I passed the Georgia test in December using the two books along with a DVD the Cobb county extension agent had for loan with $20 deposit.
Literally, the DVD was video of the review classes they have or did have before the test. The DVD covered all the chapters, they told you what was needed in each chapter.
Video was peppered with "this will be on the test & these are the terms you will need to know" from each chapter.
I went through the video while following along in the books highlighting, underlining, and taking the quiz (Test Your Knowledge) at chapter end.
I was fortunate to pass the General Standards section w/86 out of 100 & category 24 section w/79 of 100 on first try.
Good luck! - Ed
